The main function of the excavator oil-water separator filter element is to filter out moisture and solid impurities from the oil, ensuring the quality and performance of the oil.

The working principle of the excavator oil-water separator filter element involves two main steps: First, the compressed air containing a large amount of oil, water, and solid impurities enters the separator and spirals down along its inner wall. The resulting centrifugal force causes the oil and water to separate from the airflow and flow down along the wall to the bottom of the oil-water separator. This step achieves preliminary separation of oil and water through centrifugal action. Secondly, the filter element performs fine filtration. The filter element is composed of coarser, medium, and ultra-fine fiber filter materials stacked together, which offers high filtration efficiency and low resistance, allowing it to further filter out tiny water droplets and coalesce them into larger water beads. The majority of the coalesced water beads can then separate from the oil by gravity and settle into a collection tank. This step removes microscopic moisture and impurities from the oil through the fine filtration action of the filter element, ensuring the purity and performance of the oil.

In summary, the excavator oil-water separator filter element effectively removes moisture and impurities from the oil through the above two steps, protecting the excavator’s lubrication system and key components, extending the service life of the equipment, while also enhancing work efficiency and safety.
